The camera preview shows you how much of your display the camera can see. Adjust your display until all of your display can be seen by the camera. If you cannot shrink the display, move the position of the camera. For optimal performance, make sure the display fills up as much of the camera preview as possible.
Once you click the Calibrate button, a dot pattern will quickly flash and if the calibration is successful, you will proceed to mount the emitter.
If calibration fails, it is likely due to the following reasons:
1. There is not enough contrast and the camera cannot see all of the display. In this case, adjust the room lighting or brightness of the projector.
2. The entire display is not within view of the camera.
3. There is too much clutter on or around the display that causes Ubi to detect more than 36 calibration dots.
